Problems solved by technology

[0002] At present, the traditional steel casing construction method uses a large amount of steel for the steel casing, and the steel casing cannot be recycled effectively, so the cost is relatively high
Although there are also construction methods involving the recycling of steel casings in the prior art, they can only solve the problem of recycling steel casings below 30 meters. When the length of the steel casing is greater than 31 meters, or reaches 50 meters or longer, Due to the large contact area between the steel casing and the foundation soil, the traditional single method will not be able to effectively remove the steel casing.

Abstract

The invention relates to the field of steel casing construction, and discloses a recovery method for an ultra-long and super-large steel casing, comprising the following steps: A. Embedding the steel casing (1) on the foundation (9), and the upper side of the steel casing (1) Leak out of the water surface (10); B. An end cover (2) is installed on the upper side of the steel casing (1); the end cover (2) includes a cylindrical shell (21) provided on the outside, and a sealing end is provided on the inside, and the sealing end Including the conical frustum (221) and the sealing pot (222) from bottom to top, the outer side of the conical frustum (221) and the inner side of the cylindrical shell (21) are connected by a reinforcing plate (3); C. The upper end of the cylindrical shell (21) Set the vibrator; D. start the vibrator, loosen the soil near the steel casing (1), apply pressure in the steel casing (1), and remove the steel casing with a crane (7). The present invention uses a vibrator to vibrate the foundation soil around the steel casing when recycling the steel casing; combined with pressurized jacking, the recycling effect of the steel casing is better and the work efficiency is higher, and it is suitable for burying super large and super deep steel casings. Casing recovery.
